CONNECTER FOR ELECTRIC GABLES.

Application filed March 14, 1922. Serial No. 543,673.

. in driving tools; for instance, such tools as tie tampers illustrated in my Patent #1329349, dated Jan. 27, 1-920, and another use is where considerable lengths of cable are dragged about, as in mine machinery and tools and the like.

Second, to provide an improved connecter for cables which provides a very secure connection and one which minimizes the strain upon the cables and their conducting wires.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly .defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. I is a detail view of a connecter embodying the features of my invention, partially broken away for convenience in illustration and to show structural details.

Fig. II is a detail view mainly in longitudinal section on a line corresponding to line 22 of Fig. III. I

Fig. III is a transverse section on a line corresponding to line 3-8 of Figs. I and II Fig. IV is a detail section on a line corresponding to line 44 of Fig I, showing the arrangement of the connecting link or a pair of connecters.

Fig. V is a detail view of my improved connecter adapted for a branched line.

Fig. VI is a sectional view on a line corresponding to line 66 of Fig. V.

In the drawing similar reference characters refer to similar parts throughout the several views and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring tothe drawing, 1 represents a conductor cable, the cable shown being provided with three of the wires 2 as it is lntended for use with a three phase motor. My improved connecters comprise a pair of members 3 and-Lhaving opposed channels 5 for the cable and opposed channels 6 for the connecter terminal members 7 and 8.- These are of the plug andsocket type, being the same except that one is a plug and the other a socket to receive the plug. These terminal members are provided with, sockets 9 at their inner ends internally threaded to receive the clamping screws 10, I

the wires 2 being arranged through the bores 11 of the clamping screws and spread out so that they are clamped in the bottom of the sockets by means of the screws. heads of the screws are non-circular so that they may be turned down by means of a wrench securely clamping the wires. Tubular insulators 12 are provided for the terminals 7 and 8, these terminals being of soft or resilient rubber. The conductor cable 1 is also provided with a tubular casing 13 of resilient rubber.

The

The connecter members have internal lugs by the insulator 12 thereby also providing a further binding means between the parts. The latch or connecting link 17 is pivoted to one connecter at 18 and is provided with a hook 19 adapted to engage the transverse bolt 20. The connecters are thus effectively secured together and at the same time may be readily disengaged. The strain upon the cable is minimized by this connection and at the same time it is securely clamped so that the wires are not likely to be pulled from the terminals. I

The terminals are supported s9 as to yield somewhat by means of the resilient insulators so that the connecters may be dragged along on the ground or over railway ties or the like without liability of injury thereto and the insulators are not cracked or broken by such usage as would be the case if they were of hard material.

'and the connecting wires '25, shown by selves to those skilled in the art to which dotted lines in Fig. V, are connected to the wires 26 of the cable, as indicated by dotted lines in Fig. V, the wires 26 being continuous through the connecter 21.

I thus provide a branched connecter which has the advantage of securing the cable with a minimum of strain upon the wires thereof and also the other advantages, as stated, of the single line or conducting cable connecters. Other variations and adaptations will no doubt suggest themmy invention relates.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination with a conductor cable, of a pair of Y connecter members provided with clamping bolts and having a plurality of opposed longitudinal internal channels in the body portionthereof and opposed continuous channels in the arms thereof, a portion of said cable intermediate its ends being clamped in said arms, such portion being provided with a tubular casing of resilient material. connecter terminal members having threaded sockets at their inner ends, connecting wires for the wires of said conductor cable to said terminal members, clamping screws for said connecting wires, the ends of such wires being arranged through the screws and clamped in the bottoms of said terminal sockets. said screws being provided with proiecting heads, and tubular insulators ,of resilient material for said terminal members embracing the heads of said clamping screws. said insulators bein clamped in said channels.
